I'm in the process of getting my Home Assistant environment up and running, and decided to run a test: it turns out that my gaming PC (custom 5800X3D/7900XTX build) uses more power just sitting idle, than both of my storage freezers combined.
Background: In addition to some other things, I bought two "Eightree" brand Zigbee-compatible plugs to see how they fare. One is monitoring the power usage of both freezers on a power strip (don't worry, it's a heavy duty strip meant for this), and the other is measuring the usage of my entire desktop setup (including monitors and the HA server itself, a Lenovo M710q).
After monitoring these for a couple days, I decided that I will shut off my PC unless I'm actively using it. It's not a server, but it does have WOL capability, so if I absolutely need to get into it remotely, it won't be an issue.
Pretty fascinating stuff, and now my wife is completely on board as well; she wants to put a plug on her iMac to see what it draws, as she uses it to hold her cross-stitch files and other things.
I know they're gonna be a power suck lol. Three mini PCs, a SFF PC, 4-bay hard drive docking station, 8-port switch, and a RPi0w... Hoping for a max of 200W, but I suppose we'll see what happens π«€
You might need to lower your expectations
FYI - the cluster is pulling 115-140 watts.
All running multiple VMs (Docker and other) and LXC containers.
I'm impressed, honestly. I was expecting 200+ watts minimum. It'll be interesting to see the spikes as it's used over time. I am going to move the HA server (Lenovo M710q running HAOS on a Pentium G4560T & 4GB RAM) down to the cluster soon, as it's sitting on my desk at the moment...
I'm surprised! Seems like it should be more, but I haven't done any wattage calculations in a while, so maybe power efficiency really has gotten that much better.
Do you know if the drives were spun up or down at the time? I know idle vs. active makes a difference, but if they were spun down entirely, that's kind of cheating.
I watched as everything booted, didn't pull much more than 150 watts. But it'll be interesting to see how it goes over time.
Yeah... I know. π
I see your 4-bay docking station and raise my 20-bay storage server. I even stopped counting how much the hardware costs for it :p
I raise you my 72 bay monster... https://www.ebay.com/itm/126301431412
But I have 512 GB of ram in mine...
It's attached via USB to a 2014-era Mac Mini running OMV; it's a dedicated NAS and nothing else. Honestly not a huge fan of that hardware setup at this point, as the Proxmox cluster running all of my VMs and whatnot sees it drop out periodically for absolutely no reason. I've already tweaked the network adapter within the OS to stay powered on, because apparently Apple hardware has a mind of its own and just decides to shut various components off for "power saving" reasons.
The kicker is that I'm upgrading it to a 7th-gen based server soon. My dad gave me an old Pentium 4-powered HP Proliant DL110 last year, the case of which has 10x 3.5" drive bays, and is fully ATX compatible, so I'm gonna drop in a 7th gen mobo with Pentium G4560T (already have that on my desk), a newer PSU, and an HBA card. Don't need a ton of processing power for a dedicated NAS running OMV - just a lot of expansion capacity.
